Welding flux

A welding flux particularly for submerged arc welding of low alloy steels consists of by weight:- .Al2O3.4 to 15% .Mn O.2 to 15% .CaF2.35 to 55% .SiO2 and CaO.Balance in a ratio of .SiO2: CaO of 2.08: 1 to 1.1. The flux may also include metal of the same analysis as the electrode or steel being join...

More Information
Summary:A welding flux particularly for submerged arc welding of low alloy steels consists of by weight:- .Al2O3.4 to 15% .Mn O.2 to 15% .CaF2.35 to 55% .SiO2 and CaO.Balance in a ratio of .SiO2: CaO of 2.08: 1 to 1.1. The flux may also include metal of the same analysis as the electrode or steel being joined and may be produced by fusion, sintering or bonding with sodium silicate and crushed and screened to form granules. Alternatively the flux may be used as a core of a hollow tubular welding wire. HY-80 steel plates are welded using a 5/32 " steel welding wire with a single vee 45 DEG bevel groove butt joint using a D.C. reverse polarity at 550 amps. arc current and 27 volts arc voltage with the electrode moving along the weld at 20" per minute.
